This invent-ion relates to a device for warp leasing, and it hasparticular relation to novel means for effecting the separation of thewarp threads to permit the insertion of lease cords or 55 rods which areused to maintain an orderly arrangement of the warp threads, usually atthe beginning and ending of thewarp. The formation of such leases in awarp facilitates the drawing in or layingin the Warp in a reed or comb,and, in some instances, the entering of the warp through the harness ofa'loom.

The present invention is "more particularly adaptable for use in theformation of what are known as pin leases, that isto say, where thelease is so formed that the threads are separated in sets, one set foreach dent space of the reed of the loom-in which the warp issubsequently to be mounted, although, of course, it should be understoodthat the device may, undercertain conditions, be used for the formationof other types of leases if so desired.

The pin leases above referred to are used principally when the warp isplaced in a slasher preparatory to sizing the yarn. However, theinvention is also adaptable to be used in the formation of a lease in awarp prepared on a Warping machine, and will also be found to beadaptable for the formation of various other types of leases.

The principal object of the present invention is to provide a simple,yet efficient, device for effecting the formation of a lease in a warpwhereby the lease may-be formed in a simpleand expeditious manner, andby a simple series of manipulations.

A further object of the invention is to providea device for forming warpleases which may be inexpensively constructed.

The present invention contemplates the provision, in a comb or reed, ofa dent having a hook portion of novel and peculiar formation forselectively engaging the warp --to take a loose therein.

The nature and characteristic features of the invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawing forming part hereof, in which:

Fig, 7 .is a horizontal section through a portion of the reed or combshown in Fig. 1 with the warp threads illustrated in operativerelationship with respect thereto, when the first part of the lease istaken as in thestep shown in Fig. 5; and

Fig.8 is a similar view when the second part of the lease is taken as inthe step shown in Fig. 6.

It should, of course, be understood that the drawing and descriptionherein contained are illustrative merely, and that various modificationsand changes may-be made in the structure disclosed without departingfrom the spirit of the invention.

Referring more particularly to Figs. 1 to 4 of the drawing, there isthere shown one form of constructionofa leasing reed .or comb l0embodying the principal features of the present inventionandparticularly adaptable for use in the formation .of a pin lease in awarp. Said device consists of .a suitable frame ll havingside struts l2,and disposed between side struts I2, hook .dents l3 and plain dents Mare suitably spaced in alternate relationship, said dents being rigidlysecured at their lower ends in the frame ID in the usual manner ofconstruction of soldered reeds.

As there shown, each of the dents l3 and I4 comprises a thin flat stripof metal, the dents l3 being each provided intermediate its ends with ahook portion of peculiar formation. At the place where the hook portionis provided, the dent I3 is cut out as at IS, the preferred shape of thecutout being illustrated in Figs. 2 and 4 of the drawing. The cutout isso shaped as to provide a sloping or inclined margin l6 extending fromone edge of the dent to a medial point, thence extending downwardlyparallel to the side edges of the dentas at H. 50

At the lower end of the cutout I5 adjacent the edge of the dent, thereis provided an upwardly extending projection 18 which constitutes a hookadapted to function in a manner to be hereinafter more fully set forthto effect the leasing operation. It should be noted that the hookprovided by the upwardly extending projection I8 is disposed entirely inthe plane of the dent strip, and does not project beyond either sideface thereof.

The other dents M are made plain,'without any hook portions, andordinarily the dents will be disposed in spaced relationship, a hookdent l3 alternating with a plain dent 14. It will be noted that by thisarrangement, when viewed from the front and rear, the dent spaces willbe free and unobstructed, so that as long as the warp extends straightthrough the dent spaces, none of the ends thereof will be engaged by thehook portion of the dents l3.

The reed or comb formed as aforesaid is preferably open at the top topermit the ready insertion of the warp ends in the proper dent spaces,although it should be noted that, if desired, a cap (not shown) may beplaced over the top of the reed or comb, as is sometimes done in devicesof this character. In other instances, the reed or comb may have theupper ends of the dents rigidly secured in a manner similar to structureat the bottom. In still other instances, the dents may be supported attheir lower ends by suitable springs, as is commonly done in expansioncombs which permit the number of dents per inch to be varied to suit therequirement of the user.

The invention relates primarily to the construction and arrangement ofthe dents, but not to any particular manner in which they may besupported.

In the manipulation of the warp to form a lease therein, the comb orreed may be initially positioned, or shifted sidewise if necessary, tocause the warp ends which are located in each of the dent spaces to bearagainst one set of faces of the dents, as, for example, in Fig. 7. Asillustrated in Fig. 5 of the drawing, one of the supports S of the warpis now lowered from the position shown in dotted lines to that shown infull lines. As the warp is thus lowered, the warp ends in each alternatedent space will be caught by the hooks l8 of the dents l3, and the warpends which are located in the other alternate dent spaces will passfreely along the smooth faces of the dents l4 against which they bear,and a shed will thus be formed, as shown in Fig. 5, into which may beinserted the first lease rod or cord L After the lease rod or cord L isinserted in the shed formed as aforesaid, the warp may again be raisedby elevating support S to its initial position, as shown in dotted linesin Fig. 6, and the reed may then be shifted sidewise to cause the warpends, which previously bore against the smooth faces of the dents 14 tonow bear against the faces of adjacent dents l3. The support S may thenagain be lowered from the position shown in dotted lines in Fig. 6 tothe position shown in full lines, it being noted that as the support Sis thus lowered, the warp ends which encounter the hooks l8 of the dents13 will be caught in said hooks, and the other warp ends which bearagainst the faces of the dents I4 will pass downwardly without beingengaged by any of said hooks, thereby forming a new shed into which thesecond lease rod or cord L may be inserted to complete the lease.

Of course, it will be apparent that instead of raising or lowering thewarp as above described, the lease sheds may be formed by leaving thewarp supports stationary and causing the comb or reed H] to be raisedand lowered, whereby the hook portions of the dents l3 will selectivelyengage the warp ends in the same manner as above set forth to form thelease sheds; and it will also be apparent that instead of shifting thereed sidewise, as above set forth, the reed may be left stationary, andthe entire body of the warp shifted sidewise but in a contrarydirection.

It will be noted that the manipulation for the formation of the lease isquite simple and may be expeditiously performed without requiring anyparticular skill on the part of the operator; or on the other hand, thedevice may be readily incorporated in an automatic machine without unduecomplication.
